Our invention relates to the preservation of wood of all kinds from the deleterious effects of the elements as well as against the ravages of all kinds of destructive insects such as toredos, termites, etc., and it refers especially to a preservative which may be applied withtout the intervention of heat, either with a brush as for paint, or by immersion.

One of the objects of our invention is to furnish a cheap and convenient method of preserving wooden buildings,'pilings, wharves, the hulls of ships, telegraph poles, wooden silos, and wooden structures of all kinds, whether exposed or unexposed.

Another object of our invention is to provide a cheap and suitable preservative for wood which may be used as a priming coat and filler, preparatory to the application of any kind of paint with the exception of white aint.

A further object of our invention is to provide a wood preservative which may be applied easily and cheaply without the use of heat, and which will penetrate the pores of the wood and fill the same with a substance which hardens in the pores. A still further object of our invention is to provide a wood preservative which may be applied in any manner suitable to the application of paint and which will penetrate the pores of the wood to which it is applied, and carry with it certain poisons which are destructive of toredos, termites, ants, worms and other insects which destroy the wood fibre.

Our composition consists of the following ingredients in about the following proportions:

Parafiine oil 2 gallons Naphthaleneiuflzus 2 gallons Benzol 3 gallons Creosote light 2 gallons Creosote lheavy) 2% gallons Oil of coal tar 5 gallons Cement 5 pounds Hydrated lime 5 pounds Sulphur 5 pounds Paris green 2O ounces.

In the preparation of our composition, we place our parafline oil in a suitable container in which the whole of the ingredients may be thoroughly mixed; To the .parafiine oil we add the naphthalene and thoroughly mix with the parafiine oil before any other in- Application filed December 26, 1923. Serial No. 682,820.

gredients are put in. Next is added the benzol, then the creosote, both light and heavy, and last the oil of tar, keeping the mixture in the meantime in constant agitation.

After these ingredients are thoroughly incorporated, we add thereto, while the mass is in constant agitation, the cement, hydrated lime, sulphur and Paris green, in the order named. These should be added slowly, and each succeeding one should be added only after the previous one has become thoroughly incorporated with the general mixture. The last four named ingredients are first reduced to an impalpable powder.

After these ingredients are in and this mixture is thoroughly incorporated, it is ready to be placed in cans or other suitable receptacles for storage or shipment as may be desired. It will not deteriorate by time to any appreciable extent and is unaffected by climaticconditions, but it should be kept free from the air to prevent the evaporation of the volatile oils.

By the use of this composition the fibre of the wood on which it is used is penetrated and saturated with poisons destructive to the life of insects which burrow in wood, and the cement and'the lime fill the pores and harden therein, thus preventing the evaporation or dissipation of the poisons.

In giving the proportions of the various ingredients used in our composition, we desire to be understood as giving them in the quantities which we consider the best, but we do not confine ourselves strictly to these proportions, as they may be slightly varied without materially detracting from the value of the composition; and it is to be understood that in and by the claims following the description herein we intend to cover our invention in whatever form it may be embodied.

We are aware that some of the ingredients used in our composition have been and are used in the preparation of a variety of wood preservatives, but we are not aware that any or all of them have ever been used or pre ared in the manner in which we are using and preparing them. c
